Front Panel Controls and Indicators
The number of input and output buttons and LEDs that each MVX Series VGA
matrix switcher provides varies with the number of inputs and outputs.
Figure 3-1 shows the front panel of an 8-input, 8-output video and audio switcher.
Other switcher models have fewer input and/or output buttons to accommodate
the different matrix sizes that they provide.
Many of the buttons and LEDs on figure 3-1 have dual functions.

Definitions
The following Extron matrix switcher terms are used throughout this manual:
Tie —
An input-to-output connection
Set of ties —
An input
tied
to two or more outputs. (An output can never be tied
to more than one input.)
Configuration —
Consists of one or more
ties
or one or more
sets of ties
Current configuration —
The
configuration
that is currently active in the
switcher (also called
configuration 0
)
Global memory preset —
A
configuration
that has been stored. Sixteen
global
memory presets
can be stored in memory. The input and output buttons
select
preset
memory locations to load or retrieve. When a
preset
is retrieved
from memory, it becomes the
current configuration
. On each model, there
are as many presets available from the front panel as there are input and
output buttons:
•
The MVX 44 has 8 presets available on the front panel.
•
The MVX 48 and MVX 84 have 12 presets available on the front panel.
•
The MVX 88 has 16 presets available on the front panel.
On smaller MVX models, presets that are not available from the front panel
are still available under RS-232 or optional IR 501 control.
